Product details

Instrument Introduction:

The flame graphite furnace integrated atomic absorption spectrometer is a high-performance and highly reliable spectral analysis instrument developed, manufactured, and sold independently by the company after years of spectral research and development experience. It has multiple atomization methods such as flame, graphite furnace, and hydride generation to choose from.

Performance characteristics:

1. Integrated design

Adopting a series optical path design, the position of the flame graphite furnace atomizer is fixed, and the software automatically switches without the need for hardware replacement. It switches in one second, avoiding errors caused by mechanical switching and improving the stability and maintainability of the instrument.

2. Total reflection achromatic optical system

The use of concave mirrors instead of convex lenses as optical focusing devices effectively solves the problem of chromatic aberration caused by different focal points of different elements and improves the efficiency of the optical system.

3. C-T type monochromator

Adopting a 1800 line/mm grating splitting system with a dazzling wavelength of 230nm.

4. Eight Element Lighthouse

Working with one lamp, up to seven lamps can be preheated, saving time for lamp replacement and preheating, making element measurement faster and more convenient.

5. Fully automated design

Except for the power switch of the host, all functions of the instrument are monitored and controlled by a computer, and the software automatically determines the optimal testing conditions for each element.

6. USB 3.0 communication method

The industry is the first to adopt USB 3.0 communication interface, which improves communication speed and is compatible with the latest computer systems.

7. Background correction system

Dual switching and background subtraction of elemental lamp and deuterium lamp, with two background correction modes of deuterium lamp and self absorption. When the background signal is 1A, the background subtraction ability is more than 50 times.

8. The appearance adopts streamlined sheet metal process design, simple and fashionable, beautiful and generous

9. A fully functional and powerful analysis software. The user-friendly interface makes your operation easy. It can switch between Chinese and English Windows style software interfaces and run perfectly on operating systems such as Windows XP and Windows 7. It automatically performs qualitative and quantitative analysis, calculates element content, and generates test reports.

Flame system:

1. Pure titanium atomization chamber, pure titanium combustion head

Effectively prevent acid gas corrosion and have a longer service life.

2. Efficient glass atomizer

Adopting a dedicated high-efficiency glass atomizer, with high atomization efficiency and easy maintenance and replacement.

3. Quality flow controller for acetylene flow control

The quality flow controller accurately controls the acetylene flow rate with an accuracy of 1ml/min and dynamically monitors the flow rate, making it easy to use, safe, and reliable.

4. More security measures to make sample analysis safer and more reliable

1) Acetylene leakage monitoring

2) Acetylene pressure monitoring

3) Air pressure monitoring

4) Combustion head status monitoring

5) Flame state monitoring

6) Monitoring of water seal status

Graphite furnace system:

1. Integrated design

The graphite furnace power supply and atomic absorption host are located in one instrument, which shortens the cable length, reduces the electromagnetic interference of the graphite furnace power supply to the outside world, and improves the heating efficiency of the graphite tube.

2. Graphite furnace has high temperature control accuracy and fast heating speed

By using high-power transformers, micro resistor cables, and light controlled heating methods, combined with software and hardware temperature correction systems, the temperature control accuracy in the high temperature section can reach ± 1%.

3. More security measures to make sample analysis safer and more reliable

1) Cooling water flow monitoring

2) Monitoring of carrier gas pressure

3) Graphite tube temperature monitoring

4) Graphite furnace temperature monitoring

4. Automatic carrier gas flow control

The internal and external gases of the graphite furnace are all automatically controlled by the computer according to the software heating process.

5. 150 position rotary graphite furnace automatic sampler

The polar coordinate rotary table graphite furnace automatic sampler can realize the sharing of flame and graphite furnace in one automatic sampler, with high positioning accuracy, stable and reliable operation, and easy use and maintenance.
